Ukraine says it has repaid its debt of more than one billion euros to Russian gas giant Gazprom in full.
Gazprom threatened to turn off the taps if the money was not paid by the end of New Year’s Eve.
But the gas export monopoly says it is too early to talk about an end to the crisis. It says it has not yet received all the money owed and neither has a new supply deal been finalised.
It wants Kiev to agree to pay much higher prices for future deliveries, something Ukraine has not agreed to.
There are fears any cut-off could affect supplies to Europe, as happened in 2006 when Gazprom briefly stopped delivering gas to Ukraine. Gazprom supplies around a quarter of Europe’s gas and 80 percent of that goes through Ukraine.
The company has warned European customers it fears Ukraine could resume what it has in the past described as siphoning gas from transit pipelines.
